Install CO detectors per local regulations. Boiler
requires yearly maintenance, see chapter “Checks,
adjustments and fault finding”.
Operating Limits of the boiler:
Max. Boiler Outlet Temperature: 200°F (99°C)
Max. Operating Pressure: 80 psi (5.5 bar)
The hot water distribution system must comply with all
applicable codes and regulations. When replacing an
existing boiler, it is important to check the condition of
the entire hot water distribution system to ensure safe
operation.
In addition, the unit shall be installed such that the gas
ignition system components are protected from water
(dripping, spraying, rain, etc.) during appliance opera-
tion or service.

When installed according to the listed minimum clear-
ances from combustible construction, these boilers
can be serviced without removing permanent structur-
al construction around the unit. However, for ease of
servicing, we recommend a clearance of at least 24 in.
in front, on the rear and 24 in. above the top of the boil-
er. This will allow the unit to be serviced in its installed
location without movement or removal of the heater.
Service clearances less than the minimum may
require removal of the unit to service either the heat
exchanger or the burner components. In either case,
the boiler must be installed in a manner that will enable
the unit to be serviced without removing any structure
around the boiler.
NOTE:
Use of this boiler in construction areas
where fine particulate matter, such as concrete or
dry-wall dust, is present may result in damage to the
boiler that is not covered by the warranty. If operated
in a construction environment, a clean source of
combustion air must be provided directly to the
boiler.
